There are several different methods by which to manufacture methamphetamine.
One process, which police had become familiar with was that which produced
dl-Methamphetamine. Officers were instructed that the manufacturing process
could be detected by the strong "cat urine" odor produced by this
synthesis. This method, popular among outlaw motorcycle gangs, was a very
involved process which required many chemicals, a fairly elaborate "laboratory"
and about two to three days to manufacture. What is more, the dl-methamphetamine
produced in these labs could not be ingested by smoking, which limited its
appeal. According to DEA statistics, these labs account for less than 2 percent
of all clandestine laboratory seizures nationwide.

Two methods of synthesis are most popular today produce d-Methamphetamine.
This variety is at least twice as potent as dl-Methamphetamine and is much
simpler to make, utilizing commercially available ingredients. These ingredients
are often available locally without restriction. The two main "recipes"
police encounter are termed as follows.

Of these two main synthesis (or recipes), there are at least 160 variations.
Officers investigating
clandestine labs will see a variety of ingredients and apparatus used. One
constant is the use of ephedrine or pseudoephedrine. The conversion of ephedrine/pseudoephedrine
to methamphetamine is accomplished by taking an oxygen molecule away from
the ephedrine/pseudoephedrine and replacing it with a hydrogen molecule. This
molecule swap is done by virtue of a chemical reaction using anhydrous ammonia
and lithium metal (or sodium metal) or red phosphorus and iodine crystals.
The synthesis using anhydrous ammonia is referred to on the street as "Nazi
Dope" and that method using red phosphorus is called "Red-P".

Both of these recipes can produce methamphetamine, which is very pure and
can be ingested orally, inhaled (snorted), smoked or injected. The length
of time required to produce a batch of . meth is minimal and the entire process
is highly mobile making detection and apprehension more difficult. The high
produced by d-Methamphetamine is intense and generates a strong psychological
addiction. The initial euphoria can last up to 30 minutes with a subsequent
"high" which can last 18-24 hours. It is not uncommon for persons
using meth to stay up for (on the average) two weeks at a time chasing that
initial euphoria. After about two weeks with no sleep, the user's body can
no longer support the "high" and no matter how much meth they ingest,
they can no longer get high. The body is simply telling the user it needs
rest. This phase, called the "tweaking phase" can last for up to
24 hours and the meth user is very irritable, miserable and prone to violence.
Once this phase passes, the user will "crash" from anywhere from
1-3 days. This sleep will not be interrupted for even human essentials such
as urination and defecation.

Once the person awakes, if they are a "binge" abuser, they will
avoid meth for 30-45 days or more, but in a brief period of time, the psychological
addiction will draw them back. If they are a high intensity abuser, they will
awake from their three day "nap" and begin using meth immediately.
Some high intensity pattern abusers report sleeping only one to two days per
month.

The experience of the DEA Springfield, Illinois Resident Office in dealing
with methamphetamine minors trends and patterns observed nationwide. Essentially,
methamphetamine manufacture is limited initially, but soon authorities are
overwhelmed with the number of clandestine labs they are forced to deal with.
The rapid, intense proliferation of clandestine methamphetamine laboratories
is perhaps due to addictive qualities and the fact it is very simple to produce.
Consider that in FY97, the DEA Springfield RO seized only one methamphetamine
laboratory. In the following fiscal year, 48 such labs were seized. During
the 1999 fiscal year, the number of labs increased dramatically. This, of
course, denotes lab seizures, and not labs agents were aware of but were still
in the process of establishing probable cause to effect seizure and make arrests.

The initial onslaught of methamphetamine into the central district of Illinois
saw the Quincy/ Adams County area hit very hard. Soon, the location of labs
branched eastward and many "hot spots" were seen. As of the conclusion
of calender year 1999, there were few counties in central Illinois which had
not had a seizure of a meth lab by authorities. Most counties had experienced
the seizure of several labs, often loosely connected by "cooks"
teaching others and/or persons acquiring precursors for several different
labs at a time.

A. EPHEDRINE/PSEUDOEPHEDRINE
I. GRIND TABLETS AND SEPARATE
2. SOAK TABLETS WHOLE AND SEP ARA TE
3. GRIND TABLETS AND USE IN ENTIRETY
DANGERS: Unless the "cook" is using a flammable solvent and evaporates
the solvent used to separate the pure ephedrine/pseudoephedrine from the tablet
binder material with a source using an open flame, dangers are minimal.

B. ANHYDROUS AMMONIA
I. STOLEN FROM EITHER MAIN OR NURSE T ANKS
2. PLACED IN A VARIETY OF VESSELS
(Vessels have ranged from buckets, LP tanks, Coleman drink coolers, fire extinguishers,
air compressor tanks, etc. )
DANGERS: Anhydrous ammonia poses many hazards, especially when placed in improper
vessels and handled/transported by persons unfamiliar with the dangers. Anhydrous
ammonia has a boiling point of -28 degrees below zero. When a vessel containing
anhydrous ammonia is moved, the anhydrous ammonia will reach its boiling point
and pressurize. This pressurization can cause vessels to violently rupture,
or if the vessel pressurizes and does not rupture, the opening of a container
of anhydrous ammonia can cause RAPID, VIOLENT depressurization.
1. Skin
2. Respiratory
3. Eyes

C. LITHIUM METAL/SODIUM METAL
I. TAKEN FROM LITHIUM PHOTO BATTERIES
2. SODIUM METAL ORDERED FROM CHEMICAL SUPPLY HOUSES
DANGERS: Sodium/Lithium metal is HIGHLY water reactive and will burn or explode
if it comes into contact with water. Because of the moisture in your skin, it
will burn exposed flesh. Both metals will even degrade when exposed to atmospheric
moisture. That is why clan lab operators store lithium/sodium metal in solvent
prior to use.

D. RED PHOSPHORUS
1. ORDERED FROM CHEMICAL SUPPLY HOUSES
2. CAN BE RETRIEVED FROM MATCHBOOK STRIKE P ADS OR FUSES (ROAD FLARES)
DANGERS: When heated, red phosphorus emits phosphine gas which is odorless and
tasteless. Phosphine gas is deadly as it can overcome the victim without any
warning.
Note: While used primarily in the Western United States, some clan lab operators
use HYPOPHOSPHORUS ACID in place of red phosphorus. Hypophosphorus acid is a
colorless oily liquid that emits a sour odor. There is an extreme fire and explosion
hazard if the acid comes into contact with a solvent such as acetone, toluene
or Coleman fuel. Hypophosphorus acid will also emit phosphine gas and the fumes
can ignite.

F. EXTRACTION SOLVENTS
I. COMMERCIALLY AVAILABLE
2. TYPES OF SOLVENTS COMMONLY USED*:
a. Ether (Starting Fluid)
b. Coleman Fuel
c. Mineral Spirits
d. Toluene
e. Naptha
* Not an all-inclusive.list
DANGERS: All solvents are flammable. Ether is particularly hazardous as it can
cause both fire and explosion. It is said that a quart of ether can "level"
a small house.

G. HYDROGEN CHLORIDE GAS
1. COMMERCIALLY AVAILABLE
2. MADE BY MIXING SULFURIC ACID AND SAL T
3. MURIATIC ACID (HYDROGEN CHLORIDE GAS SUSPENDED IN WATER)
DANGERS: Hydrogen Chloride Gas (HCL) can be seen as a pale white smoke. It is
a poisonous gas that can cause respiratory problems and death.

B. Anhydrous Ammonia
I. Full containers (CAUTION!!!): vessels exhibiting heavy coatings of frost
on the exterior, sweating visible on the exterior of the vessel, strong odor
of ammonia.
2. Empty containers: vessels may still exhibit "sweating" if recently
used, strong odor of ammonia.
3. If LP tanks are used, brass fittings will exhibit a bluish-green discoloration.
Hoses and fittings may be present for the stealing of anhydrous ammonia and
if brass fittings are present, discoloration will be present "as noted
above. Some anhydrous thieves may use heavy "work- type" gloves, protective
goggles and a respirator of some sort.

E. Iodine Crystals
1. Small two ounce containers, large glass containers from supply houses, bottles
of 7% tinctured iodine used to make (homemade) iodine crystals.

F. Extraction Solvents
1. Starting fluid (ether) may be observed in cans, or empty cans will be found
that are "keyholed". Often cans are incinerated after the ether is
removed. Other solvents may be observed in one quart or one gallon cans. It
is not unusual for these containers to be incinerated after they are emptied.
In association with the extraction portion of this process, coffee filters saturated
in liquid smelling like the extraction solvent used may be found.

G. Hydrogen Chloride Gas
I. Since the majority of lab operators prefer to make their own hydrogen chloride
gas by mixing sulfuric acid and salt (iodized, rock, or safety salt), full and
empty containers of those items may be found. Bottles for drain cleaners containing
or once containing sulfuric acid may be present and it is not uncommon to find
several containers of iodized (table) salt in one location. The hydrogen chloride
gas generators discovered can be any type of vessel which can be sealed and
have a hose (usually aquarium tubing) inserted into it. If the "cook"
is using muriatic acid, containers may be found at the lab site.

APPENDIX
A - SEVEN VERY HAZARDOUS CHEMICALS ARE FOUND IN METH LABS

1. Sodium/lithium metal -react violently with water and can cause explosion,
fire and severe
burns. Do not use water or CO2 extinguishers to put out fires! Soda ash and
lime may be used. Sodium metal can be purchased in one pound cylinders and are
stored in kerosene. Lithium metal is extracted from lithium batteries.
2. Anhydrous ammonia -is stored at 44 degrees below zero. A mixture of ammonia
and air (between 15 and 28%) will explode. Inhalation of concentrated ammonia
vapors will cause
burns, respiratory distress and even death. Anhydrous ammonia is available commercially
in a variety of cylinders. In Illinois, meth cooks access anhydrous ammonia
from tanks at farm service businesses or from "nurse tanks".
3. Ethyl ether -an extremely flammable and explosive solvent! Concentrated vapors
can cause a tremendous explosion with a spark or flame. These fumes can cause
respiratory distress and death. Ether is typically found in labs in aerosol
cans (starting fluid). Ether can also be found in one liter metal cans or even
55 gallon barrels.
4. HCL gas -an extremely explosive gas! It can cause severe bums to the throat
and lungs as well as circulatory collapse and death. While available in compressed
gas cylinders, it is found in labs in a variety of containers and is made by
mixing equal amounts of sulfuric acid and salt.
5. Sulfuric acid -extremely corrosive and can cause severe burns from contact.
6. Muriatic acid or Hydrochloric acid -are extremely corrosive acids! They can
cause severe bums to the throat and lungs. Circulatory collapse and death may
occur.
7. Phosphene gas -In labs using the red phosphorus/iodine crystal method of
synthesis, phosphene gas is emitted from the red phosphorus. If the red phosphorus
becomes overheated, the phosphene gas can reach levels which are deadly. Phosphene
gas is odorless and tasteless.

the DEA Springfield, Illinois Resident Office, 217/492-4504.

APPENDIX
B - GLOSSARY OF METHAMPHETAMINE TERMS

METHAMPHETAMINE is referred to by a variety of street names, some of the more
widely
used are meth, crank, crystal, crystal meth, ice, speed, etc. Listed below are
some of the more common terms heard with regard to methamphetamine production.

BLISTER PACKS: The plastic/aluminum foil packaging commonly used to contain
ephedrine/pseudoephedrine based tablets.

BREAKING DOWN TABLETS: The process of breaking down ephedrine/pseudoephedrine
in preparation to manufacture methamphetamine. There exists some variations
in this process.
1. Tablets are ground up and soaked until the ephedrine/pseudoephedrine separates
from the material that holds the tablet together (binder material). Tablets
may be soaked in denatured alcohol, grain alcohol, methanal, Heet (gas line
anti-freeze), distilled water or even tap water.
The tablet waste material may be discarded (typically found in coffee filters
or saved and used for cut).
2. Tablets may be soaked in any of the above whole and the breaking down of
tablets will still occur , but will take longer .
3. Tablets may be ground and have anhydrous ammonia and lithium metal or red
phosphorus/iodine (reaction) added without removing the tablet material. The
result is the tablet material provides a build in cut.

BUBBLER: A hydrogen chloride gas generator.*

BUBBLER HOSE: A hose attached to the bubbler and inserted into methamphetamine
suspended in an .extraction solvent (often used is a gas generator or aquarium
tubing).

BUBBLING OFF: The process of using a bubbler (gas generator) to salt out the
(powder out, often called snowing) the methamphetamine.*

CONVERSION: When salting out the methamphetamine:, it is converted from a base
to a salt.*

COOK/COOKING: This refers to the production of methamphetamine or the person
who is producing it, i.e., a meth cook.

CUT: Like cocaine, refers to material, compounds, etc., which is added to cut
the meth. Agents have seen vitamin B supplements, Vitamin E, table waste (from
ephedrine/pseudoephedrine), baking powder, laxatives, and even liquid wax used
as cut.

EXTRACTION: After the reaction phase of the process, ephedrine/pseudoephedrine
is
converted to methamphetamine base. It is then placed into an extraction solvent
in preparation to being converted into salt.

EXTRACTION SOLVENT: Most common extraction solvents used are starting fluid
(ether)
and Coleman Fuel, Mineral spirits, paint thinner, charcoal lighter fluid, naptha,
have been used, and even gasoline or kerosene could be employed.

FILTER DOPE: The methamphetamine manufacturing process involves numerous filtrations.
In the final filtration, "powdered out" meth is filtered and dried.
These filters can be saved and the moisture (methamphetamine) squeezed out into
a bowl and heated in an oven or microwaved until it forms a crusty powder. This
is meth and generally produces a couple of hits. lf the filters are permitted
to dry, they are simply wetteded and the meth squeezed out as described above.

GAS GENERA TOR: A container in which sulfuric acid and salt is combined to create
hydrogen chloride gas to salt out the meth. A hose is run from the container
and placed in the meth suspended in an extraction solvent.* Gas generators are
typically made from plastic gas containers, plastic soda bottles, sports bottles,
sulfuric acid containers.

GASSING OUT: The process of using a gas generator to salt out meth.*

ICE: Ice is defined as a smokeable form of methamphetamine that is 80% or better
purity. The purity of d-methamphetamine made by virtue of Nazi Dope and Red-P
processes, can produce meth that ranges from 90-99% pure before being "cut".

KEYHOLED: Reference to cans of starting fluid which have had holes punched in
the can so
that the ether can be poured from the aerosol can. Prior to doing this the can
is inverted and the spray nozzle depressed so that the pressure is released
from the can.

LAYERED SOLUTION: This can be any solution discovered in a lab which has distinctly
different layers.

METHAMPHETAMINE BASE: After anhydrous ammonia and lithium metal (Nazi Dope)
or
red phosphorus and iodine crystal (Red-P) are added, ephedrine/pseudoephedrine
is converted to . meth base and then is added to an extraction solvent in preparation
to be converted to a salt.

POWDERING OUT: This refers to using a gas generator to convert the meth base
to salt.*

REACTION: The reaction occurs when anhydrous ammonia and lithium metal (Nazi
Dope) or red phosphorus and iodine crystals (Red-P) are added, causing a chemical
reaction which changes phedrine/pseudoephedrine to methamphetamine by removing
one oxygen molecule.

SALT OUT/SALTING OUT: The process of converting the meth base into a salt by
using a gas generator.* (Same as snowing, powdering out, etc.)

SEPARATION : The process of separating the ephedrine/pseudo ephedrine from the
tablet, binder material. (See "Breaking Down Tablets".)

SMOKING: While this typically refers to smoking meth as a form of ingestion,
it has been referred to by some clan lab operators when describing the powdering
out of methamphetamine. The gas generator produces hydrogen chloride gas which
can be seen as a pale white smoke.*
.The majority of references about the conversion phase of the process refers,
by one term or mother, to the use of a hydrogen chloride gas generator which
is the preferred method. Keep in mind that muriatic acid, which is simply hydrogen
chloride gas suspended in water, can be used In lieu of a gas generator. This
process is slower, but the same effect is achieved. Recently, agents have found
cooks placing aluminum foil in muriatic acid to expedite the delivery of hydrogen
chloride gas.

INGREDIENTS USED IN THE VARIOUS STAGES
OF THE PRODUCTION ~Most commonly used essential ingredients

CONVERSION
sulfuric acid
salt -table, rock, safety
muriatic acid*
acetone**
* Aluminum foil can be added to the muriatic acid to expedite the "powdering
out" process. The muriatic acid and aluminum foil are placed in a gas generator,
in the same fashion sulfuric acid and salt are placed in a gas generator.
** After the conversion process is complete, if the meth is off-white or perhaps
even brown (from failing to extract water during the cook) acetone can be used
to "wash" the meth and in essence, whiten the final product.

United States v. Loos, 16SF3dSO4
(7th Cir.1998)
FACTS: Quincy, Illinois firefighters responded to a fire at a residential apartment
complex
where the kitchen and living room were ablaze. After their arrival, firefighters
heard several explosions. Firemen discovered what they believed to be a clandestine
methamphetamine laboratory in a bedroom and promptly notified arson investigators
and the Quincy, Illinois Police, The responding police officer discovered cans
of ether (starting fluid) and apparatus consistent with the manufacture of methamphetamine.
The Quincy Police Department subsequently contacted DEA who responded and seized
evidence which was subsequently used to prosecute Steven Loos and Lorna Jo Taylor.
The defendants pled guilty, however later appealed claiming that a warrant was
necessary to permit a criminal investigation and that a chemical disposal squad
other than police should have been utilized.
ISSUE: Was a search warrant required to permit police officers to conduct a
search after being summoned by firefighters?
HOLDING: No.
RATIONALE: The court held that a warrantless entry by police may be legal when
there is a compelling need for official action and no time to secure a warrant.
Where a building is ablaze, circumstances are sufficiently exigent to render
a warrantless entry is reasonable. Once firefighters are in a building, they
may seize anything in plain view.

Fire officials are charged with extinguishing fire and determining the cause,
If a warrantless entry to put out a fire and determine its cause is constitutional,
a warrantless search for evidence while inspecting the premises for these purposes
is also permissible. As for the defendant's claim that the fire department should
have used a chemical disposal squad other than a police agency, the court held
that the defendants had no legitimate interest in deciding which public employees
handle hazardous substances -the hazardous waste disposal personnel or law enforcement
agents.

APPENDIX
D - OBTAINING A SEARCH WARRANT FOR A METH LAB
Law Enforcement Use only!

I. Affiant's identity, status and
oath

II. Affiant's lab experience

Ill. Investigative facts
A. Be specific
1. Be specific as to times, dates, places, sources of information and so forth.
Set forth all
the facts known to the affiant and give as much detail as possible.

B. Identify your sources
1. The source of the facts must be identified in the affidavit. Consider the
following
sentences:
a. The violator was seen leaving the supposed lab site.
b. The records of the ABC Chemical Company were reviewed and contained invoices
to the suspect's home.

2. Ask yourself: Who saw the violator leave? Who reviewed the chemical company's
records? These sentences do not tell you. Statements like these are worthless
for establishing probable cause. You must show the source for all information.
Consider the following sentences:
a. On 01-15-99, I observed the violator exit the lab, located at 123 Second
Street, Springfield, Illinois.
b. On 01-10-99, Special Agent William Brown reviewed the records of the ABC
Chemical Company and observed the records to contain invoices for precursor
chemicals which were shipped to the suspects residence located at 123 Second
Street, Springfield, Illinois.

2. Evidence that the chemicals are at the search site. The evidence noted above
can
also be used to establish this element. If it does not, you must include evidence
that. the chemicals and equipment are probably at the site to be searched.

3. Evidence that the suspects have no legitimate need for these items. Consider
the following:
a. While most elements used to manufacture methamphetamine are legally available
and have legitimate applications, you must show that the suspects possesses
these items in quantities or uses them in applications that are not of normal
use/consumption ( e.g. purchase of hundreds/thousands of pseudoephedrine tablets
at one time or in a very short period; possession of .anhydrous ammonia by persons
not engaged in farming; purchasing numerous lithium batteries; purchasing numerous
cans of starting fluid or having empty keyholed cans of starting fluid, frequent
purchases of sulfuric acid, etc.).
b. If the suspect is obtaining chemicals from a chemical supply company, is
he/she using a false name or fictitious business? A check of state and county
records may illustrate the business is a "dummy business".
c. Trash searches- The trash may contain evidence of manufacturing such as broken
glassware, items with chemical residues, coffee filters containing chemicals
and/or tablet waste material, remnants of stripped lithium batteries, discarded
tubing and gas generators, receipts, etc.

4. Suspect's history -Although not required, the suspect's personal background
may. provide some proof of a manufacturing violation, particularly if:
a. The suspect(s) have prior convictions for drug violations, especially for
manufacturing.
b. The suspect is a chemist or has had significant training in chemistry .With
methamphetamine laboratories, suspects frequently purchase general chemistry
handbooks or order books on how to manufacture methamphetamine from ads in sources
such as High Times .
c. Expert conclusions -In addition to having the expert state the chemicals
can be used to manufacture a controlled substance it may be desirable (but not
essential) to include his opinion on:
(1.) Legitimate uses -if there is a legitimate use, what quantities might be
used. For example, the normal person does not purchase hundreds/thousands of
pseudoephedrine tablets at one time or in a short time frame.
(2. ) End product -from the chemicals acquired, how much product could be derived?
(3.) Manufacturing time -How much time needed to complete one manufacturing
cycle.
(4.) Special needs -Does the process require special needs such as large amounts
of water, electricity, or any special characteristic such as odors or by-products,
i.e., things you can corroborate.

(5.) Dangerous chemicals -Ask what chemicals pose a danger to the residence
or neighbors and how much danger. What kind, i.e., fire, explosion, etc.

D. Items to be seized
Describe items to be seized in detail. Include the following:
I. The controlled substance being manufactured. 2. The chemicals and other raw
materials.
3. The equipment used to manufacture the controlled substance. 4. Paraphernalia
used to package and distribute.
5. Formulas, books or records relating to manufacturing and distribution. (In
methamphetamine cases, receipts for the purchase of essential ingredients are
very important. ).
6. Articles of personal property tending to show the identity of those having
control of the property .Bills such as those from utility companies are very
useful in establishing "proof of residency".

APPENDIX F
- SOME PERTINENT QUESTIONS TO ASK IN A METH LAB INVESTIGATION
Law Enforcement Use only!

I. Meth "cook"
-When did you start producing meth (date)? -How often did you cook?
-When was your last cook?
-How much finished product per cook?
-What was your source of ingredients? ( Persons, stores, where they were stealing
anhydrous,
etc.)
-Who assisted you (with cooks or acquisition of precursors)? -Who did you sell
to?/Who sold for you?
-Ifhe or she agrees (most do), have the cook describe their process step by
step. This is
obviously beneficial to the investigation and also aids in learning the variations
used to produce meth.

II. Witness/Co-defendant/Source of Information
-How do you know the defendant?
-How long have you known the defendant? -How long has he/she been cooking?
-Have you witnessed/assisted meth production?
-Have you acquired ingredients for the defendant? Where? How much? How often?
-Have you purchased meth from the defendant? How often? How much? Cost? Firstllast
purchase?
